Rather than queueing microtasks ad nauseam to check if a media element
has a new source candidate, let the media element tell us when it might
have a new child to inspect. This removes endless CPU churn in cases
where there is never a candidate that we can play.
This fixes a crash in box_baseline, due to cells created for
display: table expecting a box child and getting the inline node wrapper
instead.
Fixes#18972.
Core::System::mkfifo() doesn't rely on POSIX's mkfifo() and sends the
syscall directly to our system. This means that the and errno doesn't
get updated which ultimately caused the program to display an incorrect
message 'mkfifo: Success (not an error)'.
This now allows websites such as Discord, YouTube and your favourite
"Right Click" xkcd comic to open a custom context menu when you right
click. You can bypass this by holding shift, just like Firefox.
Avoid possible null optional dereference when creating border radius
clipper, and avoid creating clipper if the clip rect is empty (which
prevents some debug spam). Also remove an unnecessary lambda.
Add a helper initialize_interrupt_queue() helper to enable_irq instead
of doing it as part of its object construction as it can fail. This is
similar to how AHCI initializes its interrupt as well.
NVMe{Poll|Interrupt}Queue don't have a try_create() method. Add one to
keep it consistent with how we create objects. Also this commit is in
preparation to moving any initialization related code out of the
constructor.
Previously, we would get a line of junk pixels to the right or bottom of
the captured bitmap.
Two aspects to this:
- Use Painter's clip-rect functionality instead of trying to implement
it ourselves.
- Switch from ScalingMode::NearestFractional to ::NearestNeighbor.
Somehow, `draw_scaled_bitmap(NearestFractional)` draws outside of the
Painter's clip-rect. I can't discern any difference in behavior
between these two otherwise.
We also now use the same bitmap for drawing the grid as we used for the
bitmap, since this had issues where it wasn't drawn to the edge of the
bitmap.
Now, we write the data recieved to a file when the user drags a file
onto the Spice Viewer window. Once complete, the FileExplorer will open
with the copied file highlighted.
The old message system was very dependent on syscalls, and the overall
structure made it hard to implement new features.
The new message system is pretty expandible, where each message has its
own dedicated class. As well as this, we now use Core::File and
AK::Stream for reading and writing messages.
Using AK::Stream also allows us to change the actual data source
(in this case, Core::File) without having to update a whole lot of code
in the future.
The callee that we're passing it to expects a GCPtr anyway, so there's
no need to explicitly dereference this.

Using HashTable of grid positions to represent OccupationGrid allows to
simplify positioning code. For example maybe_add_row() and
maybe_add_column() calls are not needed anymore because there is no
Vector<Vector<bool>> that need to be resized.
No observable changes in grid layout are expected :)
It's not safe to allocate from the GC heap while in the constructor of a
GC heap cell. (Because if this ends up triggering a collection, we may
end up trying to call through an uninitialized vtable).
This was already done safely in the initialize() virtual in much of
LibJS and LibWeb. This patch moves the logic for prototypes, mixins,
and CSSStyleDeclaration as well.
Fixes a long-standing GC crash that was pretty easy to reproduce by
refreshing https://vercel.com/
This commit lets us differentiate whether access faults are caused by
accessing junk memory addresses given to us by userspace or if we hit a
kernel bug.
The stub implementations of the `safe_*` functions currently don't let
us jump back into them and return a value indicating failure, so we
panic if such a fault happens. Practically, this means that we still
crash, but if the access violation was caused by something else, we take
the usual kernel crash code path and print a register and memory dump,
rather than hitting the `TODO_AARCH64` in `handle_safe_access_fault`.
